Picture: A woman in Africa is poring water into the solar filter.http://www.treehugger.com/solar-technology/eliodomestico-solar-house-still.html?campaign=th_rss
Summary: Half of humanity is going to be effected by the water crisis that is spreading to different countries. Their water is not cleaned properly and many people are getting diseases. But, designer, Gabriele Diamanti, has found an inexpensive and easy way to change the issue. The filter doesn't use electricity, it is solar so always dependable and filters 5 liters per day. This great filter is called eilodomestico, it is an easy way to filter your water. First, you just pour the water into the spout and walk away and finish what you need to. Then, over the course of the day, it will filter using the solar power. "The heat turns the water into steam, which travels down through a nozzle and condenses against the lid of the bowl at the bottom of the still." At the end of the day, all of the water is purified. The bowl can easily be carried on one's head to bring it home.
Opinion/Reflection: I think it is really cool that someone is trying to help the problem in Africa where there is not much clean water to drink for many people. This idea seems like it would work really well, according to the article. It ties really well to our unit because we watched the Jay-Z diaries and we read about the arsenic issue in India. Hopefully this contraption will work for the people and spread around to help all of the other countries in need.
Questions:
1. Do you think this will work? Why?
2. If you were living in Africa, would you want to use it?
3. How do you think that they thought of this?
Opinion/Reflection: This is such a clever idea. This is a very good and cheap way to help people in need of clean water. I think this idea will work sufficiently. This could be really helpful for the countries that need clean water. Those countries need to start using this. This reminds me of when we watched all those videos about how countries don't have clean water, and this is helpful method for them. They should have though of this cheap method sooner.
ReplyDeleteAnswers to questions:
1. Yes, because it is not expensive and it purifies the water people need to drink.
2. Yes I would want to use it because I would be in need of clean drinking water and it is a clever idea.
3. Scientists probably thought of this by thinking and testing cheap ways to help to countries in need of clean water.
Questions:
1. Why is this not expensive?
2. Do you think the countries will agree to use this?
3. How will the countries get this eilodomestico?
OPINION/REFLECTION: I think that this is a great invention because of the problems with contaminated water in Africa, India and other such places. It is great to see that there is a cheap easy way to purify water. It is very smart to use solar panels since it is eco friendly. This reminds me of the purification experiment we just did in class and it seems that this invention and our experiment are both using the destillation process. If we ever need this in the future, it will be nice to know that something like this exists.
ReplyDeleteAnswers to Questions: 1)I do believe that this WILL WORK because we used the same technique to clean our water in class but used a bunsen burner to boil the water, not the sun's energy and solar panels. To fully purify the water they may have to do this process a few times for total safety.
2)Yes I would use this because it is an easy and cheap way to clean the polluted waters. If the water makes people sick including myself, why not?
3)I think that people have been searching for a solution that is cheap and easy to purify drinking water in poverish areas. The process of distilling water is known by scientists and a handful of people so they used this in mind to make this invention.
OTHER QUESTIONS: 1)Do you think this invention produces enough purified water to support large families?Why or why not?
2)Explain the process that is going on with this invention. Why does it work?
3)About how long do you think this process takes in precise hours?Why would it take this long?
4)Would you drink the water after the first purifying process or would you run it through a few times? Why?

ReplyDeleteO/R: I think that this is so cool. It is a creative way to allow people to have clean water. This reminds me of our lab "water water everywhere and not a drop to drink" Becuase the filter the water with heat and condensation, which is what we did with the burners. This could also help me if I ever needed clean water if our water sources were ever polluted.
Answers:
1) I think it will work, but the downside of it working is it has to be in sunlight for the solar panel to work, which would make it work.
2) I would use it because it would clean the water like it did in the lab and provide drinking water. I would also use it because it is inexpensive.
3) I think that they could have been doing something similar to our lab and realized that they could use solar power.
Questions:
Do people actually use this method? What makes it better than any other methods? How well does it clean the water? Is this method practical (fit in a certain area, easy to use, takes a short amount time, etc)?
